Discover how Voice over IP technology is transforming business communication worldwide
Voice over Internet Protocol (VoIP) has revolutionized the way companies communicate. Unlike traditional phone systems that rely on copper wires and analog signals, VoIP converts voice into digital data packets transmitted over the internet. This fundamental shift brings unprecedented flexibility, scalability, and cost-efficiency to businesses of all sizes.
Businesses save 40-60% on communication costs by eliminating expensive hardware and reducing call charges, especially for international calls.
Add or remove users instantly without new infrastructure. Perfect for growing businesses and seasonal fluctuations.
Employees can take business calls anywhere with an internet connection, using their laptop, tablet, or smartphone.

How it works and why it matters for your business
VoIP works by converting analog voice signals into digital data packets, compressing them using codecs (like G.711, G.729, or Opus), and transmitting them over IP networks. The Session Initiation Protocol (SIP) manages call setup, teardown, and features like call forwarding and conferencing.
At Netiva, we specialize in open-source platforms like Asterisk and FreeSWITCH, which give you complete control over your system without vendor lock-in. You own your data, your configuration, and your future.
